Variable Gap Magnet
Variable Gap MagnetThe redesigned Variable Gap Magnet is rugged and durable while providing excellent results as a demonstration tool.
Vibrating Strings Experiment
Vibrating Strings ExperimentThe complete solution for studying standing waves driven by a variable frequency driver.
Viewing chamber
Viewing chamberThe demonstration cuvette is made of clear plexiglass and measures approx. 9 x 11 x 3 cm. It has a rounded bottom so that there are no corners where small animals can hide, making observations easier. The transparent construction makes it possible to view the contents from multiple angles, and the cuvette is suitable for both studying and photographing collected organisms.
Ward’s® Fossil Display Pack
Ward’s® Fossil Display PackA fine display set of basic fossil types for beginning geology students, this set is mounted on a study display card with information outlining each fossil and providing key information on the groups represented.
Water Cycle model
Water Cycle modelWith this simulation model, you can recreate the water cycle and even make it rain in the classroom.
WiFi microscope 3MP w. stand
WiFi microscope 3MP w. standA neat little WiFi microscope with 3 MP resolution and stand. Easy to use for examining small details and surfaces, and includes adjustable built-in LED illumination. When mounted in the stand, allows a slightly larger working distance, and less magnification. When holding it over a surface, you can use the focusing wheel to ensure sharp images at two different magnifications. Supplied with Windows and Mac compatible software for pc use, but can also connect to Android or iPhone/iPad via WiFi.
Wireless CO₂ Sensor Pack
Wireless CO₂ Sensor PackClassroom 8-pack of Wireless CO₂ Sensors packaged in a Gratnells storage tray with custom insert.
Wireless Optical Dissolved Oxygen Sensor
Wireless Optical Dissolved Oxygen SensorThe redesigned small form optical dissolved oxygen sensor is compatible with all standard 12 mm probe classroom stands and stoppers.
Wireless Soil Moisture Sensor
Wireless Soil Moisture SensorThe Wireless Soil Moisture Sensor measures the volumetric water content (%VWC) of soil, reporting data in real time or storing it onboard the sensor’s memory for long-term experiments. Durable and easy to use, the Wireless Soil Moisture Sensor is the perfect tool for monitoring controlled experiments in the classroom and long-term experiments outdoors.
